outgoing mails are not signed Domainkey

[Brujo]

it seems that signing outgoing Mails with domainkeys is now broken (postfix)

update: in general the outgoing mails from webmail and from external Mail Client using standard ports 25 & 465 are signed but not if i use the submission port 587. For me is this a bug.

any idea?
